If you come to Oahu, Hawaii, a coastal drive tour is a must. You can rent a car and do the tour yourself, which allows for more flexibility. However, our guide talked non-stop, not even for a second, while driving. I truly admire that! The guide and driver essentially made up more than 50% of our trip. I'd love to meet them again if I come back. Haha, if you've been to Hawaii, you can't say you've truly experienced it without a coastal island tour, right? ~~~~Haha
